N2 - This work presents the results of the study of glycerol and water sorption using two complimentaryapproaches, simultaneous thermal analysis and isothermal sorption calorimetry, on zeolites differing in theframework topology and post modifications (natural clinoptilolite, protonated zeolite ZSM-5 with Si/Alratio of 50, commercial Na-mordenite with Si/Al ratio of 6.5 then modified by ion exchange for copper ions,or by alkaline etching to develop mesoporosity, and pillared mordenite). For the studied mordenites a correlationbetween texture and composition and sorption capacity towards glycerol and water was shown. Analysisof glycerol and water desorption suggests the optimal temperature range for catalytic conversion of glycerolvia dehydration and carboxylation
